PCOS, Convenience Eating And Keto..

I'm a 23 year old female diagnosed with PCOS. I'm trying to target my weight gain and hair loss symptoms by starting a Keto diet.

I've been struggling with it my first week because I have no idea how to cook. I have a full time job on top of attending college full time. I don't have a lot of time in my day and have always chose convenience foods over cooking my entire life. I welcome anyone to share quick and easy meals for a busy bee. I've never been good at cooking so I always want to stick to simple. I only need help with breakfast and dinners.

No food allergies. I don't really like eggs or mushrooms. Is it bad to be incorporating cheese into every meal? Should I invest in keto supplements?
